Considering that Air Force One runs at roughly $200,000 per hour*, Trump’s choice to attend the tournament could escalate to $12m, taking into account Secret Service protection, local policing, security measures and lodging costs.

*This cost includes fuel, maintenance, crew salaries, security, and support logistics (such as transporting armored vehicles and staff). For comparison, a regular Boeing 747 costs about $24,000–$27,000 per hour to operate.
